A partial t-spread in a projective space P is a set of mutually skew t-dimensional subspaces of P. In this paper, we deal with the question, how many elements of a partial spread Sf can be contained in a given d-dimensional subspace of P. Our main results run as follows. If any d-dimensional subspac
## Summary Patients in a teaching hospital in Scotland were given the opportunity to ask for further information relating to their periβoperative anaesthetic management. One investigator visited all of the patients preβoperatively and asked a standard list of anaestheticβrelated questions. Our obje
